Help- Suggestions for new Linksys antennas

post #1 of 17
Thread Starter 
Hey all.


I have a Linksys wrt54gl router w/ddwrt, and while it operates ok, i was just wondering if there's any benefit to getting a new pair of stronger antennas. Ive seen a bunch of the 7dbi and 9 dbi ones on ebay.

Any suggestions on which ones would give me better reception? I wouldn't mind a stronger signal when I'm at the far end of my house which is where I'm usually getting just 1 bar reception.

Appreciated.

Simply stated db relates to distance but what I think is a little more important is they type of antenna, omni-directional (most common) but if you don't need it going every direction (router is at one end of the house and you don't need signal in your yard) you can get a directional antenna which will do a bit better for your needs and security.

pretty much this^^^ plus dBi is the measuremnt of Gain or Power Gain which is proportional to range thumb.gif

Ok then ..

with those points in mind .. any new ideas for making my router the best it can be ? I definitely dont need omni signal, my router is at the far end of the house with nothing behind it .. Im just looking to make my signal stable (it usually fluctuates up and down wildly) as well as getting more range towards the end of the house. (where im usually getting just 1 bar).

Up for any ideas ... also, if anyone has some ddwrt settings that will improve the signal (does raisingthe TX power even do anything etc..) Id love to hear them !

Appreciated.

You can up the TX power and that will make a huge difference. Don't go crazy with it though, you can fry your router if you set it too high.
I think default for that router with DD-WRT is 71. You could go to 100 no problem (max is 251). When you start getting higher than that you can start having heat issues (adding heatsinks or even active cooling can let you up it even more).

I would try 90 and see how the reception is at the far end and go from there. Also set your router at the highest point you can, that will improve signal.

aslo if you up the power of the anttena and your router gets hot, i like what Linkinparkfan007 sugested in another thread, get a laptop cooler and sit your router on it tho im not sure if the wrt54gl has intake holes in the bottom, i can only see ontop for cooling.. thus it would help cooling if have an intake underneath smile.gif

The looks there is intake holes on the bottom.

Here are some other mods that people have done for cooling.

450

You can also try the Windsurfer Antenna mod that directs your wireless signal a certain way.

The 54GL does have holes in the bottom as well as the top.

I have mine actively cooled (I have some pics of it somewhere).


edit: Here is one pic of mine:

525x525px-LL-2aab3859_vbattach193879.jpeg


I have a WRT-54GL and a Vonage Router ( Linksys RT31P2). They were both getting hot sitting stacked on top of each other and I would drop connection randomly.
I bought a cheap router from craigslist for the shell and put a 80 MM fan in it. It is in between the 2 other routers after adding heat sinks and cutting some of the housing away (sucks cool air from the bottom through the 54GL and blows air through the Vonage router). I have not had a dropped connection since.



2nd edit:

Here is the setup:

______________________________________Vonage
______________________________________Fan
Modem (wish it was the same style)________54GL
